Original BIOS dump for the Dell 3405 on Compal board LA-K001P revision 1.0, packed in a 4.28 MB RAR archive. LA-xxxxP codes belong to the Compal numbering scheme, the ODM that builds many Dell notebooks and all-in-ones. The image is meant for writing to the SPI flash with a programmer when a unit fails to boot after corruption. Read and keep the existing chip contents, including service tag data, before flashing, and confirm that the PCB code and revision match and the image size suits the chip.
